ZS Pharma, a biopharmaceutical company developing novel treatments for kidney, cardiovascular, liver and metabolic disorders, today announced that it has secured a debt facility of up to $20 million with MidCap Financial. The company will use the funding to advance the clinical development of ZS-9 (sodium zirconium cyclosilicate), its proprietary drug candidate for the potential treatment of acute and chronic hyperkalemia. In June 2014, the company also raised net proceeds of approximately $112 million from its Initial Public Offering.
Under the terms of the agreement, the company immediately drew $10 million upon closing on July 14, 2014, leaving the remaining $10 million available for working capital purposes when certain development milestones are met over the next several months.
"With the proceeds from our IPO in June and this debt facility, we are now in a solid position to fund the development of ZS-9," said Todd Creech, Chief Financial Officer of ZS Pharma.
The ZS-9 clinical program is designed to investigate the treatment of acute and chronic hyperkalemia, regardless of underlying cause. ZS Pharma's first Phase 3 study, ZS003, a 753 patient randomized, double-blind, placebo-controlled study, showed that ZS-9 rapidly reduced serum potassium in hyperkalemic patients to normal levels within the 48 hour Induction Phase and then controlled potassium within the normal range throughout the 12 day Extended Treatment Phase. In addition, the study provided evidence suggesting that ZS-9 is safe and well-tolerated with an adverse event profile similar to placebo.
In March of 2014, ZS Pharma initiated ZS004, its second Phase 3 clinical trial of ZS-9. ZS004 is a randomized, double-blind, placebo-controlled study designed to confirm, over a longer treatment period, the positive results previously reported for ZS003. The Company also recently initiated ZS005, an open-label, 12 month, long-term maintenance study of ZS-9. The Company plans to file a New Drug Application with the United States Food and Drug Administration and a Marketing Authorization Application with the European Medicines Agency in the first half of 2015.
Hyperkalemia, or higher than normal potassium levels (typically defined as a serum potassium level >5 mEq/L), is a life-threatening metabolic condition that can lead to cardiac arrhythmia and sudden cardiac death. Hyperkalemia is characterized by abnormally high concentrations of potassium in the blood resulting from the inability of the kidneys to excrete potassium, impairment of mechanisms that transport potassium into cells, or a combination of both factors. The causes of hyperkalemia vary but the most common are chronic kidney disease (CKD), diabetes, congestive heart failure (CHF) and side effects from cardio-renal protective drug therapy, such as renin angiotensin aldosterone system (RAAS) inhibitors.
ZS Pharma is a specialty pharmaceutical company based in Coppell, Texas. ZS Pharma's lead therapeutic candidate, ZS-9, is an investigational treatment for hyperkalemia that is being evaluated in late-stage clinical trials to demonstrate its ability to safely and effectively remove excess potassium from the blood and maintain normal potassium levels. ZS Pharma is also pursuing the discovery of additional drug candidates that utilize its novel selective ion-trap technology for the treatment of kidney and liver diseases.
